TYPE-WRITING MCHIN E.

To all whom z't may concern:

Beit known that I, EDWARD J. SHEEHAN,

a citizen of the United States, residing at New York, in the county ofNew York and 'State of New York, have invented certain as will enableothers skilled in the art to which it appertains to make and use thesame. y

This invention relates to typewriting machines, and ,with regard tocertain more specic features thereof, to paragraphkey mechanism.

u One of the objects ofthe present invention is to provide a simple andpractical mechanism adapted'to permit the operator to regularly indenteach paragraph onf-the return movement of. the carriage tolinewcommencing position. Another object is to provide a mechanism of theabove character having few parts which will be inexpensiveto'manufacture and install. 'A further object is to provide mechanism ofthe first above-mentioned character which will be eflicient in use andreliable in operation. Other objects will be-n part .obvious and in partpointed out hereinafter.

The invention accordingly consists in the features 0f construction7combination of elements and arrangement of parts which will beexemplified in the construction herein-v after set forth, and the scopeof the 'application of .which vwill be indicated in the followingclaims.

In the accompanying drawings, wherein is shown one of various possibleembodiments of this invention,- y

Figure 1 is a side elevation partly in section of such parts of atypewrlting machine as are necessary to obtain a clear understanding ofthe present invention;

Fig. 2 is a plan view of certain parts shown in Fig. .1; and

F ig'. 3' is a rear elevation of certain parts shown in Fig. 1.

Similar reference characters refer to similar parts throughout thedifferent views of the drawings.

The present invention will be herel'hafter described with relation toits application to Specication of Letters Patent.

out departing from the scope of the invention. In the Noiseless machine,which is of mounted in a' carriage 4, traveling on a- 4 shift rail 5,with respect to the end of the i path of travel of the type. Thiscarriage :4 carries at its rear lineck stops, tabulatin'g stops andmargin stop but the latter, G, need only to be shownand considered inthisy case. Co-acting with this stop 6 isJ a. movable .stop or marginrelease lever 7 'which extends downwardly and forey and aft of themachine beneath the carriage. This lever 7 is mounted in verticaltrunnions 8, which are carried by a horizontally disposed shaft 10, topermit universal movement. The shaft 1Q has a. forwardly ex# tending arm11 which rests above a rearwardly extending arm 12 of a key lever 13pivotally mounted on a stud 14. Itl will Patented July 16, 1918. 'l

thus be seen that as the key lever 13 is depressed the arm 11 is rockedupwardly ,which will cause a rearward movement of the margin releaselever 7.

It will be noted that the coactive portion ofthe margin release lever 7is forked as indicated at 16, and the margin stop 6, which islongitudinally adjustable on its support, is provided with an extension17, a portion of which is providedwith suitable slots or a short rack inwhich a special or second stop 18 may be adjustably positioned, the stop18- being shaped to clear the forked end 16 of the margin release lever7 in both its normal and shifted positions. In other Words, in normaloperation the forked end of the margin release lever does not engage thespecial stop 18, but passes between its projections, as shown, so astoengage only the body portion of the s' op 6.

Pivoted at 19 upon the center tie member 2, and at one Side of the stop6, is an auxthe auxiliary lever 20 passing at thattime -l under the pinand being supported thereby.

This device may be conveniently operated substantially as follows: Theauxiliary lever is inoperative eXce twhen it is desired to indent aparagrap in which case the margin-.release key lever 13 is held down'while the carriage is'nbeing returned to line-f commencing position.This ycauses the margin release lever 7 to move rearward, as abovedescribed, but such rearward movement of the margin release lever causesthe 'upper end 21 of the auxiliary lever to move forward intosubstantially the position previously occupied by the forked end 16,and, since this auxiliary lever is not forked, it will then engage theauxiliary stop 18, located on. the bodyl portion of the margin stop. Themargin release key is held down until the end 21 of the auxiliary lever20 has eni gaged this stop, whereupon it is released and the parts ofthe paragraphing mechanism return to normal position, and during thesubsequent line movements of the carriage against the left margin, theend 16 of ltli'e margin release lever 7 will clear the spe- 'cial stopand engage only the main portion thereof in the usual manner.

Since the special stop 18 is adjustable on the body portion of themargin stop, it is clear that whatever this adjustment may be and alsotheadjustment ofthe stop with respect to the carriage, the special stopwill always provide a uniform indention of the paragraph' to any desiredamount.

From this description, it will be seen that f the invention comprises asimple and practlcal paragraph key mechanism adapted to n and advantagesabove set forth.

accomplish, among others, all of the objects As many changes could bemade in the above construction and many apparently widely differentembodiments of this invention could be made without departing from thescope thereof, it is intended that all matter contained in the abovedescription or shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secureby Letters Patent is :r y ay 1. In a typewriting machine, incombination, a carriage, kcoperable margin stops therefor, means torelease said stops, and auxiliary coperable indenting stops for thecarriage controlled by said means.v

2. In a typewriting machine, in combination, `a carriage, coperablemargin stops therefor, means to release said stops, and'v ynormallyinactive coperable indenting stops for the carriage, one movable" toengage the other and being 4actuated by said movable margin stop.

4. In a typewriting machine, in combination,l a carriage, coperablemargin stops therefor, one movable to clear the other, and normallyinactive coperable indenting stops for the carriage, one movable toengage the other and being actuated by vsaid movable margin stop and oneof said indenting stops bein relatively adjustable with respect to one osaid margin stops.I

5. In a typewriting machine, ,1n combina-,

tion, a carriage, amargin sto and an indenting stop movable therewlt andmeans on the machine frame movable relatively to said stops out of thepath of one and into the path of the other.

6. In a typewriting machine, in combinay,
